  • bin/: Additional application binaries directory.

  • other: License and this readme information. And /usr/share/perl5/Zevent with the entire Zevenet backend core.

ZEVENET Load Balancer Installation

Currently, there is only available package for Debian Buster, the installation is not supported out of this operating system.

There are two options to deploy a ZEVENET load balancer: The first is deploying the ZEVENET CE ISO, and the other is deploying a Debian Buster image and installing Zevenet with its dependencies.


ZEVENET CE ISO is a Debian Buster template with Zevenet already installed. It can be got from the following link, clicking on the "Download ISO image" button.

Installation on Debian Buster

If you prefer install zevenet yourself, you should get a Debian ISO installable from This installation process has been only tested with the 64 bits version.

Please, take into account these requirements before installing the load balancer:

  1. You'll need at least 1,5 GB of storage.

  2. Install a fresh and basic Debian Buster (64 bits) system with openssh and the basic system tools package recommended during the distribution installation.

  3. Configure the load balancer with a static IP address. ZEVENET Load Balancer doesn't support DHCP yet.

  4. Configure the apt repositories in order to be able to install some dependencies.

This git repository only contains the source code, the installable packages based in this code are updated in our Zevenet APT repos, you can use them configuring your Debian Buster system as follows:

root@zevenetlb#> echo "deb buster main" >> /etc/apt/sources.list.d/zevenet.list
root@zevenetlb#> wget -O - | apt-key add -

Now, update the local APT database

root@zevenetlb#> apt-get update

And finally, install the Zevenet CE

root@zevenetlb#> apt-get install zevenet


Please use the Zevenet APT repo in order to check if updates are available.
